Explore Twisted, the Python-based event-driven networking engine, and review several of its most popular application projects. It is written by community leaders who have contributed to many of the projects covered, and share their hard-won insights and experience. Expert Twisted starts with an introduction to event-driven programming, explaining it in the context of what makes Twisted unique. It shows how Twisted's design emphasizes testability as a solution to common challenges of reliability, debugging, and start-to-finish causality that are inherent in event-driven programming. It also explains asynchronous programming, and the importance of functions, deferreds, and coroutines. It then uses two popular applications, treq and klein, to demonstrate calling and writing Web APIs with Twisted. The second part of the book dives into Twisted projects, in each case explaining how the project fits into the Twisted ecosystem and what it does, and offers several examples to bring readers up to speed, with pointers to additional resources for more depth. Examples include using Twisted with Docker, as a WSGI container, for file sharing, and more.

Retired Phoenix Police Sergeant Darren Burch captivates you on a third twisted police ride-along with more outrageously macabre and riveting stories from his 30-year career as a rookie patrol officer, sex crimes detective, child crimes supervisor and homicide night detective sergeant in this compelling follow-up to the 2019 Pinnacle Award winning “Twisted But True” and the 2020 Pinnacle Award winning “Twisted But True Book II – Filling in the Cracks,” which resulted in Darren being featured on ID Channel’s American Detective with Lt. Joe Kenda. Darren’s horrifically brutal and morbidly funny true-crime stories resumes with a vengeance, starting with manic stories like, finding a severed leg in “A Dumpster Fire,” to the savagery of a triple murder in “Easter Massacre,” to acts of depravity from sexual predators in ”He’s No Angel” and “Caught Red Faced,” and even the supernatural with an inspirational tale in “Heavenly Sent.”

When a young woman clears out her deceased grandmother’s home in rural North Carolina, she finds long-hidden secrets about a strange colony of beings in the woods in this chilling novel that reads like The Blair Witch Project meets The Andy Griffith Show. When Mouse’s dad asks her to clean out her dead grandmother's house, she says yes. After all, how bad could it be? Answer: pretty bad. Grandma was a hoarder, and her house is stuffed with useless rubbish. That would be horrific enough, but there’s more—Mouse stumbles across her step-grandfather’s journal, which at first seems to be filled with nonsensical rants…until Mouse encounters some of the terrifying things he described for herself. Alone in the woods with her dog, Mouse finds herself face to face with a series of impossible terrors—because sometimes the things that go bump in the night are real, and they’re looking for you. And if she doesn’t face them head on, she might not survive to tell the tale. From Hugo Award–winning author Ursula Vernon, writing as T. Kingfisher, The Twisted Ones is a gripping, terrifying tale bound to keep you up all night—from both fear and anticipation of what happens next.
